Take a hike!

Submitted by PocketLab on Fri, 06/02/2017 - 17:51

Exploration 

As a hiker changes elevation during a hike, the atmospheric pressure will change. The air pressure at sea level, is vastly different than the air pressure at the top of a mountain. In some regions, it can be even be difficult for people who are not from that region to breathe, because they are not used to the changes in altitude. Using PocketLab, determine the relationship between elevation and air pressure.

Objective

In this experiment, students will:
1. Measure the change in air pressure during a hike.
2. Show how the change in air pressure is related to altitude.
3. Use PocketLab to better understand how an altimeter works.
